flow from 172.16.10.0 0.0.0.255 to 172.16.20.0 0.0.0.255 and 172.16.30.0
0.0.0.255 but i don’t want network to flow from 172.16.20.0 0.0.0.255 to
172.16.30.0 0.0.0.255 and vice versa, so I created the following acl,

access-list standard 10 permit 172.16.10.0 0.0.0.255

access-list standard 10 deny any.

and also i created sub interfaces on the router for interface fa 0/0

sub interface fa 0/0.1 for 172.16.10.0 0.0.0.255

sub interface fa 0/0.2 for 172.16.20.0 0.0.0.255

sub interface fa 0/0.3 for 172.16.30.0 0.0.0.255

and I have applied the above access list on the sub interface fa 0/0.2 and
fa 0/0.3, but its not working. Please help
